Who are the best powerpoint designers to work with?

I have some content in PPT and need a designer's touch to help bring it to life. Looking for recommendations on people that are good. I've used freelancers on elance and odesk in the past but would prefer to work off a recommendation instead...

Fast turnaround and low pricing at SketchDeck -- YC startup that helps to refine a lot of Demo Day pitch decks : )

You'll want to give them some general idea of what you had in mind, say by attaching one or two sample pitch decks you really liked -- with a few back-and-forth revisions, their decks turn out really well.

I run www.HighSkillPro.com which helps businesses find and hire vetted top quality service providers for things like web / app development, web design, social media, and other services (e.g. finance, law and strategy consulting). We vet, interview and reference check all service providers thoroughly.

We have just gone through our search for great PPT designers. It's harder than we thought and they are more expensive than we had expected. Happy to recommend a few superb ones. Feel free to get in touch - ania@highskillpro.com.
